The objective of this paper is to investigate the optimal deterrence p
olicy against criminals and their activities. We show that, contrary t
o court records which reveal that unsuccessful criminals are less seve
rely punished than their successful counterparts, the optimal deterren
ce policy is ''reverse discrimination''. A risk averse criminal who kn
ows that he faces a higher probability of being arrested and a more se
vere punishment if he is unsuccessful in his criminal activity, will b
e deterred to a greater degree than if a more moderate punishment is i
mposed when the outcome is less successful. We believe that policy mak
ers, courts, and law enforcement officers should consider this when ma
king decisions about criminal apprehension and punishment.
